The course is aimed at presenting the fundamental principles of earthquake phenomenology. In particular, the course will examine the relation between seismicity and faults, as they are both the results of the same dynamic process. Basics of rheology, rock fracturing, fault growing, and seismic deformation will be introduced. The course will also focus on seismotectonics. Seismic activity in different geodynamic settings will be discussed.
The scope of the course is to provide the student with a basic knowledge of the phenomenology behind seismic process. The topics discussed during the lessons will allow understanding why, where, and when earthquakes occur.

Lectures and classroom exercises
1) Rock fracturing and faults: rheology of rocks and Earth’s lithosphere; fracturing criteria and fault growing; effects of fluids on faulting; fault population; fault dynamics (stick-slip model and elastic rebound).
2) Mechanics of earthquakes: seismic waves; earthquake magnitude; seismic moment and energy; fault interaction in the seismic process (computer exercise on Coulomb stress transfer); scaling law in seismology.
3) Seismotectonics: role of geology, geodesy, and seismology to evaluate seismic deformation; seismic sequences and earthquake clustering; seismicity and geodynamics (e.g., subduction zone seismicity, oceanic earthquakes; intra-plate seismicity); seismic activity in the Mediterranean; earthquakes and tsunamis.
3) Basics of prediction and forecasting: meaning of short-, medium-, and long-term earthquake forecasting; earthquake precursors.
